Anyone have logs with cat temp at WOT pull

[Bartly]

Curious if any of you have any log files that you could share on a WOT pull that shows the catalytic converter temps. Hoping for temps related to throttle command, rpm, speed, lambda. Curious how hot the cats get with a stock vehicle, tuned vehicle and superchargers if anyone cares to send them to me. Just thought I'd ask here.

Would also like to see how they react to a partial throttle pull as well if anyone has that info.
Thanks hopefully

It's inferred so there is no PID that will tell you. Our cars do not come with EGT sensors. You should know it will infer 1600*f+ around 6000rpm and above. You will know when it happens when your a/f plummets...

^^ like he said its a calculated number. Maybe from this table. Max lambda allowed for COT is also shown in attached. I have all that shiz disabled in my tune.

Yup thats it.

To the OP, if you have cats, leave it alone, don't raise the temps and don't disable any of the 3 functions. Doing so will vastly decrease the life of your cats, regardless of whether they are OEM or hi flow. I was running a Magnaflow hi flow cast on mine and blew them out completely after 2 months, hell, it could of been less than 2 months, I just recall they didn't last long. My car was spitting out chunks of honeycomb out the tail pipe for a while...annoying rattle

Thanks for all the info. I'm not wanting to go hotter trust me. I recently saw 1900+ on my log under CATTEMP1 and CATTEMP2. Was hoping what I was seeing wasn't true. I now have a new tune, so hopefully I won't be seeing that again. Lambda was right around 1 as it was climbing and happening if I recall. Thanks again for the info.
